I love to paper piece. I LOVE not having to worry about precise rotary cutting and a 1/4 seam. It came in handy during bilateral cataract surgery when i was a one eyed wonder between surgeries! lol
The trick is to do one block over and over, it becomes second nature then. I also precut the pieces I need -- it's a rough cut to be sure. Alex Anderson's paper piecing book is great for explaining this.
